The slope of a line perpendicular to another line is the opposite reciprocal of the slope of that line. Basically, the slopes of two perpendicular lines multiply to -1. The slope of this line is -1/5. To find the slope of a line perpendicular, we need to find out what number, multiplied by -1/5, would make -1. Or, we can take the opposite reciprocal (it's the same answer). This number is 5, so the slope of a line perpendicular to this line is 5.
Answer:
303.66 in²
Step-by-step explanation:
The area (A) of a trapezoid is
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases
here h = 12.6, a = 19 and b = 29.2, so
A = 0.5 × 12.6 × (19 + 29.2)
= 0.5 × 12.6 × 48.2 = 303.66 in²
Answer:
1600
Step-by-step explanation:
Answer:
I will do a step by step explanation to help you.
First, subtract 16 from 31 so you can simplify what you need to find. We will call the unknown number X. So 5x = 15
15/5 = 3 so X = 3
Lets plug in X
3 x 5 + 16 = 31
Makes sense!
